Dephasing enhanced transport of spin excitations in a two dimensional lossy lattice

Andrei Skalkin, Razmik Unanyan, Michael Fleischhauer

Noise is commonly regarded as an adverse effect disrupting communication and coherent transport processes or limiting their efficiency. However, as has been shown for example for s…

Controlled Quantized Adiabatic Transport in a superlattice Wannier-Stark ladder

R. G. Unanyan, N. V. Vitanov, M. Fleischhauer

The Born-Fock theorem is one of the most fundamental theorems of quantum mechanics and forms the basis for reliable and efficient navigation in the Hilbert space of a quantum syste…

Comment on "Resonance-induced growth of number entropy in strongly disordered systems"

Maximilian Kiefer-Emmanouilidis, Razmik Unanyan, Michael Fleischhauer +1

We comment on the recent paper by Ghosh and Žnidarič (Phys. Rev. B 105, 144203 (2022)) which studies the growth of the number entropy in the Heisenberg model with random magn…

Quantized single-particle Thouless pump induced by topology transfer from a Chern insulator at finite temperature

Lukas Wawer, Razmik Unanyan, Michael Fleischhauer

Quantized particle or spin transport upon cyclic parameter variations, determined by topological invariants, is a key signature of Chern insulators in the ground state. While measu…

Particle fluctuations and the failure of simple effective models for many-body localized phases

Maximilian Kiefer-Emmanouilidis, Razmik Unanyan, Michael Fleischhauer +1

We investigate and compare the particle number fluctuations in the putative many-body localized (MBL) phase of a spinless fermion model with potential disorder and nearest-neighbor…

Absence of true localization in many-body localized phases

Maximilian Kiefer-Emmanouilidis, Razmik Unanyan, Michael Fleischhauer +1

We have recently shown that the logarithmic growth of the entanglement entropy following a quantum quench in a many-body localized (MBL) phase is accompanied by a slow growth of th…
